This is a tough question, as no two projects are the same. Document photography is a much faster method than scanning each page. An example would be that a traditional scanner can take ~60-90 seconds for each page at Hi-Res, with extra time required to flip the book over, turn the page and place it back onto the scanner. Photographic methods involve turning the page, ensuring it is flat and snapping the image. This takes ~5-10 seconds per page or spread. This could allow a book of ~300 pages to be captured in a little under an hour, whereas with a standard scanner, the same book could take up to 5 hours. We would be happy to meet with you to view your documents and photos and give you an idea of timeframe.
